Forward specific email to exchange

Currently I have cpanel hosting email for a specific domain. I'm wondering if there's a way I can forward any email to a specific email address to an exchange server that I would like to setup. I'm getting sick of using webmail and imap and would like for a couple people that have emails with this domain name to use exchange instead.

I'm hoping I can just use route_list in exim to do this, does anyone see a reason why that wouldn't work?

I got mine to work. I followed some of the guides out there to get a smarthost going. That seemed to be the easy part. I then learned that all I needed to do to filter and only send mail to certain users was add the "local_parts" directive to the smarthost router. The /etc/mail_users file is simply a list of mail addresses.

Now with this smart host I can forward my email to my smarthost so I can continue to test the solution all while everyone elses mail in the domain goes to the standard EXIM router for my virtual host.
